To all whom it may concern:

Be it known that I, HOWARD M. DUDLEY, a citizen of the United States, residing in the city of Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented certain new and, useful Improvements in Hosiery-Dyeing Machines, of which the following is a full, clear, and exact specification.

My invention relates to dyeing machines and refers particularly to machines suitable for the dyeing of hosieryand similar fabrics.

The dyeing of hosiery and similar fabrics when not under compression presents great difficulty, as the fabric is liable to become tangled and form masses, thus preventing an even distribution of the dyeing liquid through the fabric, producing uneven results.

My device overcomes these difficulties and presents a method whereby even and uniform dyeings may be produced upon fabrics of this character.

I obtain these desirable results by a peculiar arrangement of foramino-us members, by the use of means whereby the fabric will be continually moved preventing the formation of tangled masses and by maintaining the fabric beneath the liquid while ing continuously passed therethrough.

My device comprises, in a broad way, a series of revoluble foraminous fabric compartments containing bars or rods whereby the fabric is continuously moved during the operation in order to prevent it from being tangled by forcing the liquid through these compartments while submerged beneath the liquid.

My device also comprises a smaller testing device in which fabric may be treated uniformly with the fabric in the larger device and which can be removed from the liquid within the dyeing receptacle and examined without removing the liquid from the receptacle.

In the drawings accompanying this specification, and forming a part thereof, similar parts are designated by similar numerals.

Figure 1 is a vertical cross section of one form of my device.

The particular form of my device, as shown in the accompanying drawings, comprises a dyeing receptacle formed by the sldes 10, 11, 12 and 13, the bottom 14 and the top 15. A hollow cylindrical member 16, converges into the conical member 17 which is further extended into the cylindrical member 18. The member 18 is revoluble within the stufling box 19, which is supported by the support 20. The member 18 is also revoluble Within the pipe 21, carrying the valve 22, the pipe 21 being connected to a means, not shown, for forcing a liquid therethrough. The pipe 21 is also connected to the pipe 23, connected with a means for forcing air therethrough, not shown, and carrying the valve 24. Fixedly attached to the pipe 18 is the annular sleeve 25, having a run-way therein for the balls 26, 26. The pipe member 18 is revoluble within the annular member 27 formed of two members clamped together by the screw.- bolts 28, 28. Fixedly attached within the member 27 is the sleeve 29 having a runway therein for the balls 26, 26. The member 27 has a grease cup 30 and is supported by the support 31. Fixedly attached to the pipe member 18' is the gear wheel 32, meshing with the gear wheel 33, fixedly attached to the shaft 34 connected to a source of revoluble power.

The other end 35 of the hollow cylindrical member 16' carries a stub-shaft 36, to which is fixedly attached an annular sleeve 37 having a run-way for the balls 38, 38. An annular member 39 is supported by the support 40. Fixedly attached to the member 39 is the sleeve 41, having a run-way for the balls 38. 38. A cap 42 threads within the threaded. portion of the member 39 in order to form a liquid tight joint. A grease-cup 43 serves to grease'the balls 38, 38.

The ends 17- and 35 are connected by a.

series of parallel bars 44, 44, each bar carrying a series of outwardly extended bars 45, 45. Fixedly attached to the end member 17 is the annular end plate 46 and the end member 35 is extended into the annular end plate 47 Extending outwardly from four of the rods 44, 44 and connected therewith are foraminous plates 48, 48, 48, 48, the plates 48, 48 extending from end 46 to end 47. Extending from end 46 to end 47, adjacent to the outer ends of the plates 48, 48 are bars 49, 49, upon which the extended arms 50, 50 of the foraminous covers 51, 51 are revoluble. The other end of each foraminous cover 51 has an extended hooked arm 52 which is placeable over a bar 49 and can be maintained inthat position by means of the wing screw bolts 53, 53. The cover 51 carries a series of inwardly extended bars 54, 54. The device is thus divided into four compartments formed by the bars 44, 44, the foraminous plates 48, 48, the ends 46 and 47 and a foraminous top 51, the latter being revoluble upon a bar49 to allow the compartment to be opened for purposes of loading or removing the fabric.

The device carries a testing device comprising the side 60, the bottom 61 and the top 62. -The side 60 has a step 63 upon which rests the removable foraminous plate 64, which is held in position by the extended member 65 of the top 62, by means of the screw-bolts 66, 66. The plate 64 has a series of inwardly extended rods 67, 67. Spaced above the bottom 61 is a series of parallel rods 68, 68 carrying a series of inwardly ex tended rods 69, 69. Attached to theend 47 is the testing device container 69. Pivotally attached to the top 62 is the support 70 carrying the revoluble shaft 71, to which are fixedly attached the links 72 and 73. Pivotally attached to the other end of the link 73 is the link 74, slidable through the guide 75 and within the recess 76 of the member 69. A spring 77 abuts upon the guide 75 and the fixed collar of the link 74. The link 72 has an eye 78 in which a hooked rod may be placed. An opening 79 extends from the interior of the testing device through the member 69, and an opening 80 extends from the interior of the testing device through the end member 47.

The operation of the testing device is as follows To remove it, a hooked rod is placed within the eye 78 of the link 72 and pulled upwardly; this withdraws the bolt 74 from placement within the recess 76 of the member 69 and allows the entire testing device to be removed. The top 62 and the plate 64 are removed andthe contents taken out and 'a new charge of fabric introduced, and the moved, thus allowing the bolt 74 to enter the hole 76, thus locking the device Within the member 69. v

The dyeing receptacle has the overflow pipe 81 carrying the valve 82 and the drain pipes 83, 83, carrying the valves 84, 84.

The operation of the device, assuming it to be empty, is as follows A top 51 is opened, the proper amount of fabric introduced into the compartment, the top 51 is closed and locked by means of the bolts 53, 53. The device is revolved, until the next compartment is uppermost, and the operation repeated until all the compartments are loaded. The testing device has fabric introduced into it. The top 15 is then closed in fixed position. All the valves are closed, except valves 22 and 82, liquid is forced through the pipe 21, and the device revolved by means of the gears 32 and 33 and the shaft 34. The liquid passes through the pipe 21, the members 18 and 17 into the interiorof the revolving hollow foraminous member and thence outwardly between the bars 44, 44 into each compartment and the fabric contained therein and thence outwardly through the foraminous cover 51 into the dyeing receptacle from which it passes through the pipe 81 for continuous circulation. At the same time some ofthe liquid will pass through the foraminous plates 48, 48 into the adjacent compartment. During this operation some of the liquid will pass through the passage 80 into the testing device, through the fabric contained therein, escaping through the passage 79 into the dyeing receptacle. During the entire operation, the fabric is submerged within the liquid.

The fabric may be washed by drawing the liquid from the dyeing receptacle through the drain pipes 83, 83 and forcing clean water through the device as described above.

Air may be forced through the device, by draining off the liquid, closing all of the valves with the exception of Valves 24 and 82 and forcing air through the pipe 23.

I do not limit myself to the particular size, shape, number or arrangement of parts as described and shown, all of which may be varied without going beyond the scope of my invention as described and claimed.

What I claim is 1. In a dyeing machine, in combination, a

dyeing receptacle, two end plates connected by a series of spaced bars revoluble within the receptacle, a series of foraminous plates extending outwardly from the series of bars and abutting upon the end plates, removable foraminous' covers connecting the outer extremities of the outwardly extended plates forming a series of fabric chambers with the end plates, the series of bars and the outwardly extended plates, a series of bars extending into the fabric chambers from the series of spaced bars, a series of bars extending into the fabric chambers from the covers, means for revolving the series of fabric chambers, means for forcing a liquid through the fabric chambers and means for maintaining the fabric chambers beneath the liquid during its passage therethrough.
